The anode glow in case of neon is ____________ colour.

Open in App

Solution

In case of neon gas filled in a discharge tube the colour changes to deep red .
Thus the nature of the determine the colour obtained in the discharge tube experiment.
Hence the anode glow in case of neon is deep red colour.
